Motor lost mode structure

The present invention relates to a motor lost mold structure, and more particularly to an effect of providing a mold for casting a motor, without the need for drafting, thereby achieving an effective saving of casting man-hours and improving the quality of the casting.

According to the conventional casting method (commonly known as sand turning), the model is generally placed in a sand box that has been properly filled into the molding sand, and the sand box is usually used in combination with two or more, and the model is placed. Between the two sand boxes, after the model is placed, the constructor continues to fill the upper sand box by sand blasting to completely bury the model in the molding sand. In the process, the constructor needs to fill the sand into the second sand box and need Digging sprues, runners and venting holes. After the sand filling is completed, the constructor needs to separate the two sand boxes and take out the model (drawing). At this time, it often happens during the process of taking out the model (drawing). The phenomenon of collapse of the edge of the cavity, even if repaired, may leave flaws in accuracy, and after the model is removed (drawing), the constructor needs to return the two separate models and cast them. When casting, the metal in the high-temperature molten state is poured into the cavity formed by the molding sand in the sand box, so that the casting embedded in the molding sand can be taken out after the metal is cooled and solidified after the casting is completed.

However, in the above-mentioned casting process, the metal in the high-temperature molten state may cause the edge of the cavity to collapse during the flow, or the water vapor in the molding sand is evaporated due to the high temperature to form a water vapor, which adversely affects the casting, thereby causing defective products. The production, and the accuracy and quality of its castings are difficult to control, which is inconsistent with the pursuit of precision and quality by modern industry. Moreover, the number of steps in the manufacturing process is numerous, which not only causes the increase of working hours and the increase of cost, but also Big drawbacks.

The present invention provides a motor lost mold structure, which refers to a motor lost mold which is provided in a casting process without drafting, and is characterized in that: the motor lost mold is foamed by a foamed plastic material, and the motor disappears from the mold and has a motor. The body and the corresponding flow guiding body at the two ends of the motor body; the shaft of the motor body is provided with a shaft hole extending through the front and rear ends, and the shaft hole and the motor body are provided with a plurality of through front and rear ends and surrounding Arranging the cooling passages; and providing at least one conveying seat at the periphery of the motor body, and the conveying seat is provided with at least a first-class hole and communicating with the cooling passage of the motor body; and the corresponding flow guiding seat a shaft hole extending through the front and rear ends is disposed at a center of the body; and a plurality of inwardly extending and circumferentially arranged flow guiding channels are disposed at one end between the shaft hole and the flow guiding body; wherein the motor body has a shaft hole The shaft hole provided by the corresponding flow guiding body is a common axial state; wherein the plurality of cooling passages of the motor body and the plurality of guiding channels provided by the corresponding guiding body are phase Corresponding state; The foamed plastic material is a raw material of foamed material; wherein the motor body and the corresponding flow guiding seat system are presented by one of integral forming or mutual fitting; wherein the corresponding guiding body The plurality of guide channels are larger than the plurality of cooling channels of the motor body for circulating flow when cooling Wherein the plurality of guide channels provided by the corresponding flow guiding body and the plurality of cooling channels of the motor body are cooled, and the cooling mode is either liquid cooling or gas cooling; The plurality of guide channels provided by the corresponding flow guiding body and the plurality of cooling channels of the motor body are circulated in a spiral, reciprocating or direct current manner when cooling is performed. Wherein the plurality of cooling channels of the motor body and the plurality of channels of the corresponding flow guiding body are circular, elliptical, square, elongated or polygonal or any of them Presented in a combination.

The main purpose of the present invention is to provide an effect for casting a motor part without performing a draft, thereby achieving an effect of effectively saving casting time and improving the quality of the casting.

Since the motor lost mold structure of the present invention refers to a motor lost mold which is provided in the casting process without drafting, the motor lost mold is foamed by a foamed plastic material, and the motor has a mold disappearing a motor body and a flow guiding body corresponding to the two ends of the motor body; a shaft hole extending through the front and rear ends is disposed at a center of the motor body, and the plurality of penetrating front and rear ends are disposed between the shaft hole and the motor body a cooling channel arranged around the motor; and at least one conveyor seat at the periphery of the motor body, and the conveyor seat is provided with at least a first-class hole and communicates with the cooling channel of the motor body; and the corresponding diversion A shaft hole extending through the front and rear ends is disposed at a central portion of the seat body; and a plurality of inwardly extending and circumferentially arranged flow guiding passages are disposed at one end between the shaft hole and the flow guiding seat body, thereby providing When casting a motor, there is no need to perform a drafting operation, thereby achieving a motor lost mold that effectively saves casting time and improves the quality of the casting.
